Y My present n' l tes o brick i achines, and or particularly an: I

proved inverter foruse therein; I

1 In the manufacture of brick with the use of molds, an important operation is the placing of a pallet on the mold and the turning ofthe m'old over so. as to hung the mold to a position ion top of the pallet. "After this operation is performed, the mold is removedfrom the pallet, leaving the green bricks in position on the pallet, which pallet. and molds are. then sent. thru the dryer.

This operation has heretofore been performed by hand, even though it has been attempted. to manufacture bricks in" this manner by mechanical means and the cost of such operation is exceedinglyhigh and great I part of the workman. Y

strength and-endurance is necessary on the In my present invention I havegdevised an improved mechanism for receivlng pallets onwhich are placed molds filledwlth green brick and which will invert the moldv so .as to ."have the same readily removed from- '25 engagement with; both the pallet and the green brick associated therewith.v

" -5-Fig. 3 is a plan view partly'in which block or blocks will be engaged by the on-coming mold next to be operated on, and I am enabled thereby to give suflicient verter and this construction removes one of the most serious diflicultles encountered n prior devlces.

Further, in my present invention I.

devised means, forgiving that portion of the invertercarrying the mold, an initial movement in advance of the oncoming stream of l molds to; allow the rotatiorrof the mold about an axis'without dangerof the rotating mold interfering with or being interfered 'by'thenext succeeding mold. I

'Re'ferring to the drawings,10 designates frame members constituting a base, these ,frame members being spaced apart'f'rom each other, as shown in Fig. 2, and on'jsaid" I 1 base are bearings 11 in alignment with each other. In the aligned bearings is rotatably mounted a shaft '12,.the ends or th'e'shafts extending outwardly beyond the bearings.

shown in Fig. 4 so thatas the first filled mold 54 or the next succeeding mold 541's moved onward in the stream of molds, the

left-hand end of such mold will engagewith the outer face of the block 53, this condition being present in the referredto Fig. 4. At this time there may or may not be a mold 54 in the inverted position, as shown in- Fig.

4. It is assumed that there is not. Therefore, the mold 54 shown to the right of the block 53 in Fig. 4 will engage with said block 53 and move same to the'left as shown 1n Fig. 4 until such block reaches the position carried by such frame members and will move the frame members 13 to the left as shown in Fig. 1, until the right-hand end of theslot 42 in the link 44 engages with the bolt 43 and the right-hand end of the mold .54 within the rectangular frame is in the position indicated in the dotted line des ignated by the numeral 60 in Flg. 1. Continued movement to the left of the connecting rod 29 will cause a rotation of the lever 25 on the shaft 22 and the pawl 31 engaging with the ratchet 24 will cause a rotary movement of the gear 21 in the direction of the arrow shown and thru a quarter of arevolution. The diameter of the gear 21 being twice that of the pinion 20, the rotationof the gear 21 thru a quarter of a revolutlon, will cause a corresponding rotation of the pinion 20 thru a half revolution but in the opposite direction therefrom, as indicated by the arrow marked thereon. The rectangular frame, of which the trunnions 17 form a part, will, therefore, be rotated from the positions shown in Figs. 1 and 5 into the position shown in Fig. v4 where it will be observed that the mold 54is now positioned with its open end down and with the newly made brick therein resting on the pallet 55.

At this time, also, the right-hand end of the block 53 is shown separated from the next mold 54 in the oncoming stream of molds. When the connecting rod 29 moves to the leftdthe gap between the right-hand end of the block 53 and the next mold 54 will be.

closed up and when movement is given to the oncomingstreamof bricks 54, it is obvious that the mold 54 in the inverted position, as shown in Fig. 4, will be moved completely out of the rectangularframe and onto the supports 49, as indicated to the left of Fig. 5. Fi om the position indicated in revolution to invert said mo lds. I

' 3. In an improved inverter for brick I Fig. 5, the left-hand mold will be lifted oif the supports 49 to devices for. removing themold 54 from the newly formed brick,*thereby leaving such newly formed brick on the pallets 55. Thesequence of operation above described may be continued indefinitely.
